What are the downsides of “Unlimited/Unmetered bandwidth” VPS providers?

Question

I recently checked out DreamHost's Dedicated VPS plan which comes with supposedly unlimited bandwidth.I am unable to find any direct speed metrics on their site (as opposed to DigitalOcean, 1Gbps, but bandwidth adds up).Any DreamHost Dedicated VPS users here that can chime in on their experience?Any other "Unlimited Bandwidth" providers that you recommend?What should I watch out for when picking the right unlimited bandwidth provider?

I like digging for cheap hosts for hobby projects and will try to help from that experience. I never used DreamHost specifically but tried a lot of the ones on MetaDedi[1]. There you will find best dollar-ram, dollar-cpu and unlimited bandwidth.
For bandwidth, I would be careful to read their Acceptable Use Policy and check if it is really unmetered or "fair usage". For completely unmetered and free usage, look for seedboxes (things people host torrent on). Outside of this, I can recommend Hetzner from my experience. Other options are providers from the Tor wiki, used for exit nodes, and so on. Note that the network quality will vary a lot as you go to cheap free unmetered vs restrictive metered. Some of the restricitve metered will also sell plans with 100TB+ monthly, making them great for hosting too.
